Our take
Pick Apollo.io if you're outbound reps who will spend credits on emails and phones in one seat. Pick RB2B if you're on a b2B team with a site and a Slack who will act on inbound visitors. Skip Apollo.io if you're a sender who only need unlimited warmup inboxes (Instantly). Skip RB2B if you're on a outbound team who need a name + domain finder (Hunter).
